Panic - Watchdog Timeout: no checkins from watchdogd in 185 seconds

All of my information is backed up in iCloud. I just removed Norton from my MBP, hopefully that is what is causing my problem. I notice that it pops up after I get the Watchdog Timeout. If it continues I will take it into the Apple store. Thank you for the update.

As I said on page 1, remove all security and cleaner apps.

It is step one of any Mac diagnostics and then leave them off permanently .

Even if it is not the cause if this problem they have no place on any Apple product.

Hi - I'm new to this message string but have been having (I think) the same problem... "Watchdog timeout..." since I bought this computer back in February. At first it would happen rarely - once every few days, and sometimes would go a few weeks, but for the past couple of days it's now every few minutes - mostly when I'm working in Lightroom. Don't know if anybody out there knows if there's an issue with Lightroom that might be causing this???

I did try to download and install the 10.15.4 combo update today, after reading that advice here. But I got an error message: "macOS Catalina 10.15.4 Update can't be installed on this disk. The volume does not meet the requirements for this update." I have macOS Catalina Version 10.15.7. Is there some other option I should try?

I'm by no means a computer / IT technician. My computer diagnostic skills and background consist of rebooting the machine and then yelling at it. Or vice versa. It seems like there should be a better way of getting help than having to put out messages into the "fellow users universe," and hoping that somebody out there has a clue what to do. Argh. Thanks to anybody out there for your answers. :)

I posted in this thread earlier. My problem with this crash turned out to be hardware. It resolved after replacement of the logic board and solid state drive. The problem started while I was working in Lightroom CC Classic with a spinning beachball that I couldn't clear without a restart.

I don't know what LR could have done to break hardware and I would guess this is just coincidence.

But it's an odd coincidence...

How wonderful of them....Based on your feedback to others I've deleted Webroot security. So far ok, no freezing since I posted the original question about Big Sur. I'll post back in a couple of days with an update in case others are interested.

I've been having these over a year from occasionally to every hour or so, but many signs point towards hardware failure:

* screen flickering increased from sporadically to constantly in a year (never dropped my mac (again) after apple replacement.

* batteries started bloating pushing screws out the mac (again, after another apple replacement)

* heat sync connector to mainboard is loose, was loose for over a year but seemed ok, crazy glued it tight 🤣

* pandemic replacement prevention syndrome struck 🙈

So I'd advice prayer if you're religious...

This problem has gone off the boil generally with latest macOS updates, (to Big Sur where possible) removing all security and cleaner apps and avoiding USB hubs. Have you gone through the previous pages?

Get Etrecheck from App Store

Give the tool full disk access

Nobody who is an expert will help you on a thread this age.

Good feedback

obvious comment is get the 10.15.4 "combo" update.

https://support.apple.com/downloads/macos

There is now a Big Sur forum

https://discussions.apple.com/community/mac_os/big-sur

I would try there

Decided to try caffeinate and I have been successfully running for 5 hours with no freezing or reboots.

do you think my prblem as per photo is the same? thank you:)

What means this message?

no checkins from watchdogd in 310 seconds

Incremental updates often patch the existing OS. They can be corrupted even with verification.

The Combo is a full copy of the current OS and is preferred by many experienced users
